Steel fiber-polyvinyl alcohol fiber concrete and preparation method thereof
The invention relates to steel fiber-polyvinyl alcohol fiber concrete and a preparation method thereof. The polyvinyl alcohol fiber reinforced concrete comprises a polyvinyl alcohol fiber reinforced concrete body, an upper steel fiber layer distributed in the polyvinyl alcohol fiber reinforced concrete body and a lower steel fiber layer distributed in the polyvinyl alcohol fiber reinforced concrete body. Raw materials for preparing the concrete body comprise polyvinyl alcohol fibers, cement, sand, stones, a water reducing agent and water. The upper steel fiber layer and the lower steel fiber layer are respectively composed of steel fibers. The weight percentage ratio of polyvinyl alcohol fibers, the cement, the sand, the stones, the water reducing agent, the water and the steel fibers is (1.3-3.9): (488-520): (558-603): (1150-1208): (3.2-6.3): (120-180): (18.84-25.12). Based on the steel fiber-polyvinyl alcohol fiber concrete provided by the invention, the steel fiber layers are arranged in the concrete body prepared from the polyvinyl alcohol fibers, so that the mechanical properties such as splitting tensile strength, breaking strength and compressive strength of the steel fiber-polyvinyl alcohol fiber concrete are greatly improved compared with those of polyvinyl alcohol fiber concrete.
本发明涉及一种钢纤维‑聚乙烯醇纤维混凝土及其制备方法，包括：聚乙烯醇纤维混凝土本体、分布于混凝土本体内的上层钢纤维层以及下层钢纤维层，混凝土本体的制备原料包括以下组分:聚乙烯醇纤维、水泥、砂、石子、减水剂以及水，上层钢纤维层和下层钢纤维层分别由钢纤维组成，聚乙烯醇纤维、水泥、砂、石子、减水剂、水以及钢纤维的重量百分比为(1.3～3.9)：(488～520)：(558～603)：(1150～1208)：(3.2～6.3)：(120～180)：(18.84～25.12)。基于本发明的钢纤维‑聚乙烯醇纤维混凝土，在聚乙烯醇纤维制备的混凝土本体中设置钢纤维层，使得钢纤维‑聚乙烯醇纤维混凝土的劈裂抗拉强度、抗折强度、抗压强度等力学性能相比聚乙烯醇纤维混凝土有很大提升。
